- This invention relates to electric batteries and more particularly toimproved means for supporting the cells of a multi-cell dry bat-" teryandinsulating them from one another.

5 Heretofore, corrugated cardboard has been used as a liner to supportthe cells of a bat- V tery and also to provide channels extending 7battery, during assembly or while soldering connections between thecells, and occasional- 1y bridge thev space between the adjoining edgesof two cells, short circuitingthem and.

reducing the voltage and life of the battery; Any leakage of electrolyteor other accumulation of moisture at theadjoining lower edges of thecells will also result in teriorationof the battery. 3 One of theprincipal objects of this inven tion is to more effectively-insulate thecells from one another, so that suchshort circuiting shall be much lesslikely to occur.

Suitable insulating means may be provided to insulatethe sides of the container electrodes 15 from tubes 16 are closelyfitted to the outer cylindrical surfaces of the electrodes 15 and are ofsuch length that they will project slightly beyond both ends of thelatter when the cells I are properly "assembled in place. a p

The improved liner L is provided with:

raised portions or cell-supporting means at intervals on itsinner face,leaving depressed portions maybe formed in numerous ways to producevariously sha ed means adapted to support the cells an I As shown, the

liner L board orthe'like which has a layer 19 of corv ru'gated cardboardor the like glued-or'otheri Another object of this invent-ion is topro-- vide an improved cell-supporting liner that wise united thereto,the two layers being imwaterproofing composition such. as paraffin,asphaltum', or scale wax. 7 By means of a suitable press, hecorrugations of ,the layer 19 j are crilshed longitudinally andtransversely to flatten certam corrugations '20 entlrely and otherspartially as at 21, leaving spaced provide the desiredcell-supports.Shallow channels 23 are left between the flattenedcorrugations, thechannels between the partially 4 flattened corrugations communicatingdlrectl with the deeperchannel portions 23'. between the raised portionsor upstandmg parts of corrugations forming the cell-supportmg v bosses220 3 It, will be seen that the number of bosses equals themumber 0tcells in the battery,' I0o' Theraised I leave sealing spaces j whatsmaller area than the bottoms of the zinc cans 15 and bear against thecentral portion of the bottoms of the latter, leaving a sealing space 24around or adjacent the periphery of said bottoms. The flattenedcorrugated portions about the bosses provide surfaces below the tops ofthe bosses to engage and support the lower ends of the tubes 16 whichinsulate the cells fromone another. The bosses thus support thecellsinwardly above the ends of the tubes, thereby increasing theinsulating gap between the bottom ends of adjoining cells so that piecesof metal or moisture in the spaces below the plane of the tops of thebosses will not short circuit adjoining cells.

I one another at all points.

After the liner and the cells have been assembled in'the case asdescribed, suitable insulating and sealing composition S is in a heatedand fluid condition is poured into the spaces between the cells and runsalong the channels 23 under the lower edges of the tubes 16 into thechannels 23 beneath the cells,:

solidifying therein and in the spaces 24 about the eriphery of thebottoms of the zinc cans,

furt er preventing short circuits by moisture or pieces of metal.Finally, a suitable plastic sealing composition T may be flowed overproof sheet and a facing sheet, the corrugated sheet having grooves andcrowns upon which the jackets rest, the crowns having portions raisedabove the rest-portions to extend into the open ends of and position thejackets, the grooves between the crowns permitting the filling to passunder and into the acket.

4. A dry battery comprising a plurality of cylindrical dry cells, tubessurrounding and extending. below said cells and insulating them from oneanother laterally, and a liner having bosses projecting into the tubesand against the bottoms of the cells, said bosses being channeled toreceive sealing composition in the channels.

- 5. A liner for electric batteries comprising a sheet of corrugatedpaper having depressed portions extending transversely andlongitudinally of the corrugations to provide spaced cell-engagingbosses on one face of said sheet, each of said bosses being of such areaas to extend over a plurality of corrugations and the channelstherebetween.
